The best help I got was using a 5mm forward cleat position, and 5mm shorter left crank. A spacer alone might be better for you. At any rate, you need to go through the whole pedal stroke and try to compensate for ~50% of the difference... don't try for 100%, and make sure that you don't cause some parts of the stroke to be even worse! The power phase is the most important part to get right.
That's a good question. I know in a standing position, it's all vertical. I don't know about sitting on the bike, though. That might change things. Once I find a fitter, I'll have to ask them about that.
My next question is this--if they put shims in, will it still allow for float in the cleats? I have a lot of float in my cleats because to further complicate things, my left knee is mostly trashed (3 surgeries).
